MTM Scientific Shortwave Loop Antenna Kit
Shortwave loop antenna KIT allows you to build a tuned loop antenna for indoor reception of shortwave radio broadcasts over the frequency range of 4 MHz to 15 MHz

Randmon wire antennas
This is probably the oldest SWL antenna design. It is often called a long wire though a true long wire is cut to a specific frequency and is at least one wave length long at that frequency

Random wire antenna for shortwave listening
it would be best to use a 9:1 transformer to match the random wire to the 50 ohm feedline

Receiving loop antenna for 160 meters band
I wanted to explore the possibility of having at least better receive

Monopole Antenna TFM T2FM T3FM
Terminated Folded Monopole Antenna TFM T2FM T3FM The Terminated Folded Monopole (TFM) is a derivation of the TFD, and it is usually implemented as a vertical antenna over an RF ground plane or a radial system
